Virtual Guard Bands

1. A system, comprising: a first base station of a plurality of base stations; a second base station of the plurality of base stations; and a radio resource scheduler at a coordinating node configured to: identify radio frequency bands in use by the first base station, identify a radio access technology in use at the first base station, determine that a desired band is adjacent to the identified radio frequency bands in use, identify virtual guard bands based on the radio access technology and the determination made that the desired band is adjacent to the identified radio frequency bands in use, and share the virtual guard bands with the second base station, wherein the first base station and the second base station are each in communication with a core network over a first radio access technology (RAT) and are also each allowing a user equipment (UE) to have connectivity with the core network over a second RAT, thereby providing a lower noise floor for adjacent in-use frequency bands for the plurality of base stations, and wherein at least one of the first and second RAT is a 5G RAT.

2. The system of claim 1 , wherein the virtual guard bands are allocations, priorities, reservations, or scheduling instructions for avoiding certain radio resources, radio resource blocks, or frequencies.

3. The system of claim 1 , wherein the radio resource scheduler is configured to identify radio frequency resources in use by nearby base stations or other nearby sources of interference.

4. The system of claim 1 , wherein the virtual guard bands are shared across multiple base stations.

5. The system of claim 1 , wherein the virtual guard bands are shared across multiple base stations using communication between the multiple base stations.

6. The system of claim 1 , wherein the radio resource scheduler is configured to dynamically turn virtual guard bands on or off, or dynamically increasing or decreasing the size of the virtual guard bands.

7. A method for providing a lower noise floor for adjacent in-use frequency bands at a base station, comprising: identifying, at a coordinating node, radio frequency bands in use by a currently-operating base station; identifying, at the coordinating node, a radio access technology (RAT) in use at the currently operating base station, wherein the RAT is a 5G RAT; determining, at the coordinating node, if the radio frequency bands in use are adjacent to each other; assessing, at the coordinating node, a nearby radio frequency environment for interfering frequencies; identifying, at the coordinating node, based on the determined radio access technology and the determination made that the radio frequency bands in use are adjacent to each other, a virtual guard band of radio resources within the allocated frequency band that cause less interference to transmissions in the in-use radio frequency band; identifying, at the coordinating node, a radio resource that should not be used and communicating the radio resource that should not be used via an X2 protocol message to a second base station; and installing, at the base station, rules in a scheduler to reduce use of the identified virtual guard band radio resources.

8. The method of claim 7 , further comprising assigning, at the coordinating node, frequencies for use by at least two base stations of a plurality of base stations in adjacent cells, such that the frequencies used by the at least two base stations of the plurality of base stations do not overlap.

9. The method of claim 7 , further comprising dynamically turning the virtual guard bands on or off, or dynamically making the virtual guard bands larger or smaller in size.

10. The method of claim 7 , wherein the base station is in communication with a core network over a first radio access technology (RAT) and providing connectivity for a user equipment (UE) to the core network over a second RAT.

11. The method of claim 10 , further comprising increasing utilization of resource blocks in a middle or far end of an allocated frequency band relative to a set of frequencies in the virtual guard band.

12. The method of claim 7 , further comprising sharing, at a base coordination node, the virtual guard band information across multiple base stations using an X2 protocol.

13. The method of claim 7 , further comprising using, at the coordinating node, an inter-cell interference cancellation (ICIC) or enhanced ICIC (eICIC) time domain coordination technique.

14. The method of claim 7 , further comprising lowering a noise floor on leading and trailing edges of a mid band of an in-use frequency band at the base station.

15. The method of claim 7 , further comprising lowering a noise floor for leading edge of an access link filter by assigning fractional frequencies for use on a lower end of a mid band, thereby sending downlink transmissions via an isolated portion of the mid band.

16. The method of claim 7 , further comprising scheduling, at the coordination node, resource blocks for use at least two base stations of a plurality of base stations.

17. The method of claim 7 , wherein the scheduler is a Wi-Fi scheduler, a Long Term Evolution (LTE) scheduler, or a combined Wi-Fi and LTE scheduler.
